SetSolid()

SetSolid() defines the manner in which collisions between this entity and others are handled. SetSolidFlags() can be used to tweak behaviour further.

Note:Behaviour can change subtly depending on whether the object is colliding or being collided with.

SolidTypes

SOLID_NONE

The entity does not generate its own collisions. Depending on the MoveType, its origin may still collide with brushes but will Touch() unreliably.

Tip:Use SetMoveType(MOVETYPE_NOCLIP) to completely disable all movement collision.

SOLID_BSP

The entity has a brush model defined by the map. Collides with SOLID_BBOX and SOLID_VPHYSICS objects, but not other SOLID_BSPs.

SOLID_BBOX

The entity collides with an axis-aligned bounding box. Collides with everything. Required for hitbox tests.

Tip:Use UTIL_SetSize() to define the extents of the box. But remember to stop calling it if the entity changes to another SolidType, or you will get a crash that disappears when a debugger is attached!

SOLID_OBB

SOLID_OBB_YAW

The entity collides with an object-aligned bounding box.

OBB_YAW restricts orientation to the Z-axis.

SOLID_CUSTOM

TestCollision() is called every frame to handle collisions.

Todo: Relationship with FSOLID_CUSTOMRAYTEST and FSOLID_CUSTOMBOXTEST?

SOLID_VPHYSICS

Use VPhysics for collisions. Collides with everything. Call VPhysicsInitNormal() or VPhysicsInitShadow() if you use this!
